First lady Michelle Obama's first of three outfits under intense scrutiny this inaugural weekend is as American as Coach leather - a deep blue number by Coach creative director-turned-fashion-designer Reed Krakoff.

Mrs. Obama held her family Bible for her husband's official, legal swearing-in today, as per the Constitution, clad in an almost royal blue dress with a cinched waist and A-line skirt made of what looked like a silky material with a jacquard pattern, topped with a same-color knit bolero-style cardigan with three-quarters-length sleeves.

The White House confirmed it was by Krakoff, whose clothes Obama has worn before during the past four years, via the White House pool reports on the lightning-quick swearing-in in the Blue Room.

Mrs. O's fashion choices are a priority with America's billion-dollar fashion industry, most of which is watching intently what the first lady is wearing for today's ceremony, and Monday's public swearing-in at the Capitol, and at the inaugural balls in the evening.

Usually, the attention is on the latter two outfits only, but this is one of those rare occasions when Inauguration Day falls on a Sunday (seven in history) so there are two ceremonies and thus more outfits.

Also of interest: what Obama daughters Malia, 14, and Sasha, 11, are wearing. Today, Malia chose a dress of electric blue and black panels and black tights, while Sasha picked a silhouette notably like mom's - a sleeveless dress in rosy-pink lace cinched at the waist with a wide sparkly gold belt.

During the first inauguration in 2009, the girls' outfits were proudly claimed by various American apparel brands, who reported they promptly sold out what was available online.
